Dolomites, Italy.

The Dolomites (Italian: Dolomiti; Ladin: Dolomites; German: Dolomiten; Venetian: Dołomiti: Friulian: Dolomitis) are a mountain range located in northeastern Italy. They form a part of Southern Limestone Alps and extend from the River Adige in the west to the Piave Valley (Pieve di Cadore) in the east. The northern and southern borders are defined by the Puster Valley and the Sugana Valley (Val Sugana). The Dolomites are nearly equally shared between the provinces of Belluno, South Tyrol and Trentino.

Monument Valley USA

Monument Valley (Navajo: Tsé Biiʼ Ndzisgaii, meaning valley of the rocks) is a region of the Colorado Plateau characterized by a cluster of vast sandstone buttes, the largest reaching 1,000 ft (300 m) above the valley floor. It is located on the Arizona-Utah state line (around 36°59′N 110°6′W), near the Four Corners area. The valley lies within the range of the Navajo Nation Reservation and is accessible from U.S. Highway 163.

California's Colorado Desert.

California's Colorado Desert is a part of the larger Sonoran Desert, which extends across southwest North America. The Colorado Desert region encompasses approximately 7 million acres (2,800,000 ha), reaching from Northwest Mexico border regions in the south to the higher-elevation Mojave Desert in the north and from the Colorado River in the east to the Laguna Mountains of the Peninsular Ranges in the west. The area includes the heavily irrigated Coachella and Imperial Valleys. The Colorado Desert is home to many unique flora and fauna, many of which can be found nowhere else on the planet.

Bavarian Forest, Germany

The Bavarian Forest (German: Bayerischer Wald is a wooded low-mountain region in Bavaria, Germany. It extends along the Czech border and is continued on the Czech side by the Šumava (Bohemian Forest). Geographically the Bavarian Forest and Bohemian Forest are sections of the same mountain range. A part of the Bavarian Forest belongs to the Bavarian Forest National Park (Nationalpark Bayerischer Wald) (240 km²), established in 1970 as the first national park in Germany. Another 3,008 km² belong to the Bavarian Forest Nature Park (Naturpark Bayerischer Wald), established 1967, and 1738 km² to the Eastern Bavarian Forest Nature Park (Naturpark Oberer Bayerischer Wald), established 1965. The Bavarian Forest is a remnant of the Hercynian Forest that stretched across southern Germania in Roman times. It is the largest protected forest area in central Europe.

Aurora over Norway

An aurora (plural: aurorae or auroras; from the Latin word aurora, "sunrise" or the Roman goddess of dawn) is a natural light display in the sky particularly in the high latitude (Arctic and Antarctic) regions, caused by the collision of energetic charged particles with atoms in the high altitude atmosphere (thermosphere). The charged particles originate in the magnetosphere and solar wind and, on Earth, are directed by the Earth's magnetic field into the atmosphere. Most aurorae occur in a band known as the auroral zone, which is typically 3° to 6° in latitudinal extent and at all local times or longitudes. The auroral zone is typically 10° to 20° from the magnetic pole defined by the axis of the Earth's magnetic dipole. During a geomagnetic storm, the auroral zone expands to lower latitudes.

Mount Bromo

Mount Bromo sits in the middle of a vast plain called the "Sea of Sand" (Javanese: Segara Wedi or Indonesian: Lautan Pasir), a protected nature reserve since 1919. The typical way to visit Mount Bromo is from the nearby mountain village of Cemoro Lawang. From there it is possible to walk to the volcano in about 45 minutes, but it is also possible to take an organised jeep tour, which includes a stop at the viewpoint on Mount Penanjakan (2,770 m or 9,088 ft) (Indonesian: Gunung Penanjakan). The viewpoint on Mount Penanjakan can also be reached on foot in about two hours. From inside the caldera, sulfur is collected by workers.

Dalarna, Sweden

Dalarna is a historical province or landskap in central Sweden. Another English language form established in literature is the Dales. Dalarna adjoins Härjedalen, Hälsingland, Gästrikland, Västmanland and Värmland. It is also bounded by Norway in the west. Borders of the province mostly coincide with the modern administrative Dalarna County (län).

The word "Dalarna" means "the dales" (valleys). The area is a popular vacation destination for Swedes from the south, who often travel there to relax during summer vacations, drawn by good fishing lakes, beautiful campgrounds, and deep forests. Many such Swedes own or rent a second residence in Dalarna, where they are likely to have a vegetable garden and apple trees. In mid-June, summerfest celebrations and dances are held in many of the small villages and, of course, in the larger cities

Melissani Cave, Greece

Melissani Cave (Greek: Μελισσάνη) or Melissani Lake, also Melisani is a cave located on the island of Kefalonia, northwest of Sami, about 5 km SE of Agia Efthymia, NE of Argostoli and NW of Poros. The Ionian Sea lies to the east with the Strait of Ithaca. Forests surrounds the cave and the mountain slope is to the west. Near the cave is the entry to the cave with parking lots and is passed almost in the middle of the main road linking Sami and Agia Efimia especially to the northern part of the island.
